I RESS PLATE FOR RAIL FISHPLATES.

Application filed September 24, 1925, Serial No. 58,423, and in Germany December 9, 1924'.

plate illustrated in. the accompanying draw-' ing and described in the following specification and claim.

In the drawings in which the same reference characters are applied to similar parts,

Fig. 1 shows a side elevational view of my improved press plate. Fig. 2 is a side elevation of adjacent rail ends with their appurtenant fishplates including the press plates of the present invention.

Fig. 3 is a plan view of the same. Fig. 4is a cross sectional view taken in the plane of the rail joint.

Referring now in'detail to the several ligures,-'

The pressplate A is formed on that side which bears against the fishplate with a surface slightly curved lengthwise presenting its convex side toward the; fishplate. On the other side the pressplate isreinforced by a rib a and has two oblon holes I) corresponding with the fishplate oles.

plates one on each side of the rail and are fastened tightly by means of two bolts 1) going right through the web of the rail, both fishplates, and the pressplates as shown in The pressplates A are mounted on fish-- Figs. 1,2,3. The fishplates (a), owing to the slightly curved surface of the pressplates are pressed tightly'against the web surfaces of the rail at the rail joint and are thereby held rigidly in place.

The pressure exercised upon the fishplate (c) at the rail joint (S) absorbs the vertical play-of rail ends caused by the variation of loads, thus softening to a great extent and even eliminating altogether the shock which is so harmful to the railway 5o rolling stock and the upper part of the cross tie, without influencing. the capability of rails to expand or contract longitudinally owing to changes of temperature.

I claim:

In' a rail joint construction which includes fish plates crossing the joint between the rail ends, a rigid press plate having a convex side pressing against one of the fish plates adjacent the joint between the rail ends, 00 and havin apertured ends out of contact with said sh plate in' the initial position of said press plate when the convex portion thereof is in untensioned contact with said fish plate, the apertures in said "ends being in registry with existing bolt holes insaid fish plate, the bearing point of said pressplate being adapted to be drawn into active ressure against said fish plateby bolts passin through registering apertures in said fis plates and press plates, for slightly flexing the fish plate rail-ward at the middle, maintainingthe intermediate part of said fish plate in forcible contact with the edges of the rail webs at the rail ends.

In testimonywhereof I have aifixedmy signature.
